It is thus evident that the plant will thrive almost anywhere in 

 the Island if the water supply be sufficient and the soil well 

 drained. The best method of treatment is probably to grow it as 

 hedges, which are easily managed and clipped. It may also be 

 planted along roads, jungle edges, &c.. but should never be mixed 

 with the tea, as the young leaves are very like those of tea, and a 

 twig or two of camphor will spoil a whole break of tea. 



The following analyses of two soils at Hakgala — on one of 

 which (A) camphor does very well, on the other (B) only modera- 

 tely — will help to guide to the selection of suitable spots : — 



CAMPHOR SOILS. 



" Six samples of soil were received from Mr. Nock at Hakgala, 

 which represented the character of the soil and sub-soil, where 

 camphor trees grew well and only fairly well. 



" 7/0. 7 /I, represents a section 15 inches deep between trees 

 showing the best growth, viz., 20 to 25 feet high and 12 to 15 feet 

 in diameter at five years and nine months from the time of plant- 

 ing. The surface soil here is about I foot deep. It is composed 

 of agglomerated particles of dark brown colour and yellow frag- 

 ments of decomposing gneiss. It is very rich in nitrogen and the 

 lower oxide of iron, has a fair amount of lime, but is deficient in 

 potash and phosphoric acid. 



"No. 2 A, representing the upper 6 inches, is of a dark brownish 

 colour when dry, and is almost entirely composed of the agglo- 

 merated particles mentioned in No. I A and rootlets, &c. The 

 analysis shows it to contain the bulk of the nitrogen, and an ex- 

 cess of the lower oxide of iron, but it is deficient in potash and 

 phosphoric acid. 



No. 3 A, represents the sub-soil at 15 inches deep or 3 inches 

 below the actual surface soil.' It is composed of yellow pieces of 

 decomposing light-coloured gneiss, more or less bound together 

 with a clayey matrix. It also contains a fair amount of nitrogen 

 and rather more phosphoric acid and potash than the surface soil, 

 and would be fairly easily penetrated by roots. 



"No. I B. — This is taken from a section 15 inches deep, where 

 the camphor is only doing fairly well. The plants five years and 

 nine months old are from nine to ten ft. high and 6 to 8 ft in di- 

 ameter. It is more finely divided than No. I A, and is of a lighter 

 brown colour. Chemically, it is also somewhat poorer, though 

 containing a good amount of nitrogen. Lime and mineral plant 

 food generally may be considered deficient, especially potash, and 

 this no doubt accounts for the poorer growth of the camphor trees 

 in this part. 



"No. 2 B, representing the top 6 inches, is a dark coloured loam, 

 somewhat richer in nitrogen and phosphoric acid than No. I B, 

 but is very poor in lime, magnesia, and potash. 



No. 3 B, representing the sub-soil 15 inches from the surface, is 

 a yellow loam much more finely divided than No. 3 A, but other- 

 wise of somewhat similar composition. When wet it is of a re- 

 tentive clayey nature requiring drainage.
